smb2_find_context_vals(9)

💖 NAME 💖

smb2_find_context_vals — bestie, this one hunts down a particular context info inside an open request 🔍✨

So this page lives in the Kernel API Manual, and it's all about searching an smb2 file open (create) request buffer for one specific context name. It's giving "where's my specific little guy in this giant buffer" energy and honestly? iconic 🎀

---

✨ SYNOPSIS ✨

struct create_context * smb2_find_context_vals (void *open_req , const
char *tag , int tag_len );

---

🦋 ARGUMENTS 🦋

• open_req — the buffer that's holding your smb2 file open (create) request 💌 that's the haystack, basically
• tag — the context name you're searching for, like the name tag at a party 🏷️
• tag_len — the length of tag, bestie, don't forget it, it's literally the size of the thing you're looking for 📏

---

🌸 RETURN 🌸

You get back a pointer to the requested context 🫶 — but heads up:

• it's NULL if the context isn't found, or an error pointer if the name length is invalid 😭

So yeah, lowkey always check what came back before you go dereferencing it, okay? 💅
